SAE Update - May 2023 - 22

TECH FOCUS:
VEHiCLE DyNAMiCS AND NVH
25 years and counting
for SAE's Noise Academy
I believe that summer on a
Friday morning I did go to the
SAE office in Warrendale (I had
been there before that also) to
see Tom. Tom introduced me to
his new SAE staff, Kevin Perry
and said that we have a plan. We
think you can help us with that.
That Friday was Kevin's 5th day
at SAE.
The plan was to start the
Academy program in the
Professional Development
Group. They felt NVH would be
best one to start this with.
Although we discussed some
different areas of NVH and
divided the ground vehicle NVH
into three groups (powertrain,
interior, and exterior/passby), it
was felt to have the first
Academy in the interior area,
and then to add another one,
and so on. That is how I got
involved, and SAE's first
Academy preparation got
started. SAE 1st Engineering
Academy (The Vehicle Interior
Noise Engineering Academy,
Emphasis on Acoustical
Materials) was held on July 13-17,
1998 in Ypsilanti, Mich. Next
year, The Powertrain Noise
Academy was added, and since
then both Academies run
parallel (we call separate tracks)
22
May 2023
with a few topics taught together. The lead Instructor
for the Powertrain Noise Academy is Alan Stuart. I
am going to speak for the Vehicle Interior Noise
Academy, and I am sure the Powertrain's procedure
is very similar.
What are some specific technologies studied in the
Academy?
The objective of the Academy is to be a very intense
course work and application or case studies covering
various areas of acoustics/NVH that affect the sound
and vibration in a vehicle. This includes fundamentals
of acoustics, sound, sound intensity, sound power,
instrumentation and measurements, sound quality,
numerical methods, and sound package materials.
(For Powertrain, the fundamentals of acoustics,
sound, sound intensity, sound power,
instrumentation and measurements, sound quality
were common, and then specific items to powertrain
such as powertrain noise-source mechanism and
controls, diesel engine noise, accessory drive,
mountings, their noise sources and control). The 8:30
a.m. to 5 p.m. course work is supplemented with
instrument manufacturers' workshops where they
show the latest instrumentation with the principles
on how they work, numerical method workshop,
sound quality presentation, and a field trip to a test
facility for NVH measurements. These evening
workshops and field trips are done jointly for both
tracks. We still follow the same general procedure
with changes made as appropriate and necessary as
vehicle design and technology changed.
What are your responsibilities?
My assignment was to develop the course work,
syllabus, etc., identify instructors who are going to
